2011 Subaru Outback

2011 Subaru Outback

Launched in Europe in 1996, the Subaru Outback pioneered the ‘Crossover’ concept, combining the comfort, interior space and superior on-road handling of a family estate, with the off-road capability and ground clearance of a sports utility vehicle. This special blend of abilities has now been further refined.

The new Subaru Outback is longer, wider and taller than the model it replaces. It is also more capable and more engaging to drive on-and off-road, and offers increased space and comfort for all occupants.

While it retains the bold, assured stance of its forebears, the new Outback boasts a distinctive new ‘face’. There’s a prominent grille which features Subaru’s now-trademark ‘wing’ motif. This bold detailing, coupled with a pair of ultra-modern, three-dimensional headlamps, gives the go-anywhere vehicle a refined yet purposeful look.

In profile, the Subaru Outback’s premium feel continues thanks to muscular, flared wheel arches, standard-fit 17-inch alloys, and a chrome-framed glass-house. Its roofline sweeps towards the rear, where it meets new body-coloured D-pillars.

On the inside, you’ll find a sophisticated interior design that perfectly complements the new Subaru Outback’s subtly muscular exterior lines. Subaru’s design team focused heavily on producing a feeling of spaciousness and quality and, thanks to several improvements such as increased seat adjustability, softer cushioning and reductions in NVH levels, the Subaru Outback’s cabin is an even more luxurious and cosseting place in which to travel.

The 1,998cc diesel, which has a six-speed manual gearbox, produces a maximum of 150ps and a top torque figure of 350Nm.

Boasting completely re-engineered suspension and a new all-steel unitary structure, the Subaru Outback’s handling and stability have been greatly improved. The presence of the Japanese firm’s highly acclaimed AWD system will also reassure buyers that it is sure-footed in all weather conditions.

STYLING AND DESIGN

Clearly inheriting the dynamic ‘crossover’ styling of its predecessors, but with a bolder and more distinctive silhouette, the new, fourth-generation Subaru Outback projects greater presence, both on- and off-road. The increased length, width, height and wheelbase of the vehicle provided the Subaru design team with an opportunity to give the Subaru Outback a more muscular and expressive design.

The upright front grille, which shares the Subaru family’wing’ motif, is placed more prominently and in a higher position, imparting a more robust, taller look to the vehicle. The distinct, three-dimensional shape of the more angular headlamps, with separate, circular fog lamps positioned at both ends of the ample bumper, conveys an increased sense of stability.

The sides of the vehicle are now a more prominent feature of the overall design, thanks to pronounced and muscular new wheel arches that hint at the Subaru Outback’s go-anywhere, All-Wheel Drive underpinnings. The edge of the glass-house is framed by chrome-plated mouldings to reinforce a premium-quality feel.

The roofline tapers subtly to the rear, where it meets new, body-coloured D-pillars (in previous-generation Outback the D-pillars were clothed in a black-panel to visually extend the glass-house). This new design feature emphasises the evolution of the exterior design and augments a cohesive sense of solidity.

With the all Subaru Outback, 17-inch alloy wheels are fitted as standard.

More space inside new, high-quality cabin

A sophisticated interior design harmonises with the Subaru Outback’s subtly muscular and purposeful exterior lines, and endows the much more spacious cabin with a true sense of quality.

The design team’s key mantra was “Active and Quality Feeling”, and while exploiting the enhanced cabin space available within the new bodyshell, it concentrated on detailed attention to ensure easy-to-use functionality for the driver and passengers, and maximum comfort for extended journeys. Double-seals on all doors and windows enhance refinement by reducing the intrusion of wind noise.

The all-new, larger front seats offer excellent comfort and support, with 10-way power adjustment on the driver’s seat (including lumbar support), and four-way power adjustment on the passenger seat. The front seats feature 20% softer cushions and 10% softer backrests.

The driver’s seat benefits from more adjustability, with a 10 mm increase in fore/aft slide range, 20 mm more height movement, a 2 degree increase in cushion tilt and 20 mm lumbar adjustment. Rear-seats passengers are also offered enhanced comfort, with the 60/40 split backrest reclinable over a 20 degree range.

Facing the driver, a new instrument cluster features four dials outlined in aluminium rings, and the new three-spoke steering wheel is leather-wrapped, with integrated audio and cruise controls, and a wider range of adjustment – 40 mm for both reach and rake.

The Subaru Outback comes with leather upholstery as standard.

COMFORT AND CONVENIENCE

The stylish, more spacious and high quality interior of the new Subaru Outback is comprehensively equipped to ensure maximum comfort and convenience for driver and passengers.

Self-levelling suspension, acknowledges the Subaru Outback’s long-standing popularity as a load-lugging workhorse or tow car. However hard the car might be working, inside the temperature can be carefully regulated by dual-zone, fully automatic air-conditioning incorporating an anti-dust filter and heating ducts to the rear passenger footwells.

A premium audio system, with a radio / CD player, six speakers (including two tweeters) and steering wheel-mounted remote controls, is standard. For the new Subaru Outback, radio reception has been significantly improved by the fitting of two high-performance antennae within the rear window glass.

The audio systems are MP3-compatible and a Bluetooth hands-free system is fitted. Voice activation from the hands-free microphone allows users to make phone calls and operate the audio appliances.

Facing the new Outback driver, the new instrument panel integrates clarity, functionality and a visual richness in keeping with the premium character of the new model. Four dials are ringed in aluminium and feature an additional liquid crystal display panel in the centre. The dials and the display are illuminated constantly, even in daytime, to improve visibility. The dials appear white with the ignition off and turn light blue with the ignition on.

When the ignition is switched on, the gauge needles sweep to the maximum position and then quickly return to zero – heightening the excitement and anticipation of the journey to come. A glow indicator and diesel particulate filter warning light are added part of the package.

The new Multi-Information Display (MID) is positioned on the centre stack’s upper surface so that it can be viewed from all seats. The MID shows ambient temperature, fuel consumption information (instantaneous fuel efficiency, average fuel efficiency and driving range to empty), passenger seatbelt warning lights and a digital clock.

Major controls in the Subaru Outback are laid out to minimise both the intrusion into the driver’s line of sight and the time when the driver’s hands must be off the steering wheel. Minor controls and switches are positioned to optimise ease-of-use.

The Subaru Outback’s comprehensive list of standard equipment also extends to automatic operation of headlamps and windscreen wipers, cruise control, front and rear electric windows (with auto up/down function on the driver’s door), a glass ’tilt-n-slide’ sunroof, and heated leather seats with memory function.

PRACTICALITY AND STORAGE

The cabin of the Subaru Outback is longer, wider and taller than that of its predecessor, allowing improvements to be made in comfort and practicality. The interior also demonstrates lessons learned in Subaru’s latest ‘packaging innovation’ research programme.

Larger seats are fitted to make best-use of the increased space around each occupant. The space between the front seats has increased by 30 mm and the space between the front and rear seats is increased by 62 mm. The rear seat backrest is split 60/40% and folds flat to offer the best people/cargo carrying versatility. With the rear seats upright, cargo capacity is increased by 67 litres to 526 litres, compared to the previous model.

Larger rear doors result in improved access to the rear seats, and detailed attention to the window shapes and pillar layouts ensures a greater feeling of space and light for the rear seat occupants in the new Subaru Outback.

While the width and height of the luggage bay were increased, the depth of the lip between the rear bumper and cargo was reduced slightly to ensure it is easier for users to load and unload heavy items when lifting them into the interior. The tailgate, which is 33 mm wider and 45 mm taller than before for easier access, features an electromagnetic switch for easy opening with a light touch, aided by twin supporting gas struts.

The new front seats have concave backrests to provide extra knee space for rear seat occupants. The rear seat features a folding centre armrest with twin cup holders, and the backrests can be reclined for greater comfort during long journeys. A remote one-touch mechanism conveniently located in the cargo bay side panel enables the backrests to be folded flat in one simple operation from the rear tailgate when loading long items.

Inside the new Outback designers also paid attention to create generously sized, easy-to-use storage space for smaller items – with capacity increased by 39 litres over the previous model.

The glovebox will accept 31 CDs, while the new double-decker centre console, which can accommodate 22 CDs, incorporates a 12V power supply and AUX audio input socket.

Two cup-holders are provided alongside the centre console, while a 500 ml plastic bottle can be stored in all door pockets. A 50 mm thick box of tissues can also be accommodated in the front door pockets. A central overhead console is provided for storage of sunglasses and small items.

ENGINES

This 1,998 cc diesel is based on the Subaru ‘Boxer Diesel’ introduced in March 2008 – the world’s first horizontally-opposed diesel engine for volume-produced passenger cars. It produces a maximum output of 150 ps and maximum torque of 350 Nm between 1,800 and 2,400 rpm.

For the 2011 Subaru Outback, this unique engine benefits from several technical refinements and enhanced environmentally-friendly features. The shape of the piston crowns has been changed for a wider, shallower design. This, in conjunction with improvements made to gas flow within the combustion chamber, have improved combustion efficiency and reduced the production of particulate matter. A ‘lift sensor’ has been added to the variable nozzle turbocharger for more precise control of the vanes.

The glow plugs have been changed from a metallic type to a ceramic type, raising the maximum operating temperature and providing better start-up at cold temperatures.

Control of the fuel injection has been optimised and the intake manifold has been redesigned in resin for improved airflow for improved torque characteristics and fuel efficiency. An added benefit of the new resin construction is the 1.5kg weight reduction over the previous aluminium version.

A single exhaust silencer has been used to optimise engine output and noise levels, while also saving weight. The addition of a vibration absorbing structure in the middle of main exhaust pipe also reduces noise levels.

The Subaru Boxer Diesel is fitted with a closed-type diesel particulate filter (DPF) that features a honeycomb shaped filter made of silicon carbide. The DPF, which is positioned low down with the turbocharger to maintain the car’s low centre of gravity, improves engine combustion efficiency and reduces particulate matter in the exhaust, further enhancing environmental friendliness.

And finally, the exhaust gas recirculator (EGR) cooler has been enlarged to improve the system’s efficiency by 12% – lowering NOx emissions to ensure that the new Outback complies with Euro 5 exhaust gas regulations.

TRANSMISSION

Standard transmission for 2.0-litre diesel model is a new manual six-speed unit. This compact transmission is the same length as the previous five-speed unit and weighs just five kg more.

Improvements featured in the new transmission include a cable-type linkage and a carbon synchronizer for the first and second ratios, constantly-engaged synchromesh for reverse gear, to improve the shift feel, and optimised lubrication paths for reduced friction losses. The broader ratio coverage provided by the six-speed unit delivers better fuel economy, plus improved drivability and quietness at higher speeds.

Full-time ‘Symmetrical’ AWD – the Subaru hallmark

The Subaru Outback incorporates the latest version of Subaru’s Symmetrical AWD (All-Wheel-Drive) system, giving the new model all the traction advantages for which the brand is famous.

This is an evolution of Subaru’s original full-time AWD system, which has a well-proven ability to provide real driving pleasure, superior driving performance and long-term reliability.

The four-wheel drive is delivered by a ‘Centre differential AWD with viscous LSD’ system. This combines a bevel-gear-type centre differential with the basic 50/50% front/rear, torque distribution and a viscous coupling limited slip differential. When a front wheel or rear wheel slips, the viscous coupling raises the torque distribution to other wheels to ensure optimum traction.

For maximum driving safety the Subaru Outback is equipped with Subaru’s VDC system. This is an electronic stability control (ESC) programme that closely monitors vehicle behaviour and automatically corrects excessive understeer and oversteer by braking individual wheels and/or reducing engine power, ensuring that the vehicle follows the course intended by the driver for maximum safety.

RUNNING GEAR

Following the strong tradition of the ‘Subaru Dynamic Chassis Control Concept’, engineers devised and developed the chassis and running gear for the Subaru Outback to feature many new and updated components. Their aim was to create a new Subaru that was exceptionally comfortable and safe to drive for long periods, and over many years of ownership, while also guaranteeing good drivability, high performance and genuine motoring pleasure.

To reduce noise, vibrations and harshness (NVH), and to enhance ride comfort, the engine mounting structure has been entirely renewed, for the first time since the Subaru 1000 model of 1966. An all-new ‘Cradle Mount System’ was adopted where the engine and transmission are mounted on a sub-frame – rather than directly to the bodyshell. This system brings numerous benefits.

The sub-frame is attached to the bodyshell using rubber bushes, tuned to dampen different frequencies of vibrations generated by the engine, transmission and suspension. For example, the main cushion rubber uses a liquid-filled type of bush, and the engine is supported on the subframe at four widely-spread points.

In addition, the front suspension and the power steering are mounted on the sub-frame, so that potential vibrations from the road surface are not easily transferred to the bodyshell or the car’s occupants – improving ride comfort and refinement.

When combined with the AWD drivetrain, the new Outback’s 200 mm ground clearance enables the vehicle to tackle rougher ground with ease.

New front and rear suspensions

For the new Outback, Subaru has adopted a revised MacPherson strut front suspension, with the lower arm mounted on the sub-frame for greater stability. Steering response is enhanced, and quietness is increased by reducing vibrations. The thickness of the stabiliser (anti-roll) bar is increased, improving roll stiffness without requiring a change to the main spring rates. Road-holding during cornering is enhanced (thanks in part to a wider track), while smooth ride comfort is retained with extended wheel travel and optimised geometry.

At the rear, new ‘short height’ compact double-wishbone suspension is used to minimise intrusion into the cabin or cargo space. For maximum refinement, all the suspension links and the rear differential are installed on a new sub-frame. Large bushes are used between the sub-frame and the bodyshell to minimise transfer of NVH.

To achieve an ideal ride/handling balance, new low-friction type front dampers are fitted. At the rear, the Subaru Outback is fitted with specially tuned dampers with a self-leveller function to ensure consistent ride, regardless of payload.

Electric power steering for improved fuel economy

In order to improve both steering feel and fuel economy, a new rack-and-pinion steering system with electric power assistance has been adopted. The system is mounted on the front cradle frame at four points, which increases the rigidity of the steering system, and enhances its initial response to driver inputs. Compared to the outgoing Outback, a quicker ratio is used for more immediate steering response.

New electronic parking brake and hill-hold function

The all-disc braking system, with ABS and EBD (Electronic Brake-force Distribution) as standard, has a linear feel with retardation corresponding closely to applied brake pedal pressure. A redesigned master cylinder gives a 30% faster response to driver inputs on the brake pedal.

Brake Assist is also standard, developing maximum stopping power automatically when the system detects emergency application of the brakes.

For the Subaru Outback, an innovative electronic parking brake is used. Controlled by a dashboard mounted switch, the new system does away with the traditional hand brake, freeing up cabin space and allowing a cleaner, less cluttered centre console design. If the doors are closed and the driver’s seatbelt is fastened then the parking brake will automatically release when the driver operates the accelerator pedal.

The new braking system also introduces a ‘Hill-Hold’ function. When the vehicle is stopped on a slope of 5% or more this feature will hold the vehicle on the brakes for one second after the driver removes their foot from the clutch – long enough to move it to the accelerator without rolling back; a feature that is particularly useful when towing.

Wheels and tyres

The standard wheel and tyre combination on the Subaru Outback is a 17-inch alloy wheel with 225/60 R17 tyre.

STRUCTURE AND SAFETY

As well as ‘new-look’ styling, larger dimensions and new suspension, the new Outback has a completely reviewed and re-engineered bodyshell. The all-steel unitary structure is revised to enhance ride, handling and refinement, while also delivering the highest level of crash safety performance. The new Subaru Outback’s sister model, the new Legacy – with which it shares a chassis and body – was recently awarded a 5-Star Euro NCAP crash safety rating, confirming that Subaru’s structural and safety engineers have achieved their targets for this new model.

Newly developed, the bodyshell is both lighter and stiffer, featuring ring-shaped reinforcement frames – ‘circular links’ – joining the A, B, C and D-pillars with cross members at roof and floor level. This creates a series of ‘circular links’ which strongly protects the cabin occupants. Ultra-high-strength steel plate (980 Mpa level) is used at key portions of the bodyshell to achieve strength without adding significantly to overall weight.

By fully exploiting the structural characteristics of the newly adopted sub-frame mounting system, the front body structure is redesigned to improve the rigidity of the front suspension installation and to enhance impact resistance as well as steering response. These improvements, and reinforcement of the engine bay bulkhead and toe board areas, were accomplished while also saving 6 kg from the front body panels.

The rear floor structure has also been optimised to accommodate the new sub-frame and to reduce weight while increasing rigidity, further improving rear suspension characteristics and vehicle drivability.

Delivering superior crash safety protection

Using the advanced ring-shaped reinforcements throughout the Subaru Outback bodyshell enhances collision safety and resistance to impacts from all directions. In addition, the newly adopted sub-frame mounting system contributes to an enlarged front-end crush zone, further improving occupant protection.

During a front-end collision, the new front sub-frame deforms in a controlled manner and pushes the power unit to the rear and downwards. As a result, the rearward movement of such a large mass dissipates impact energy and assists the efficient absorption of collision energy by the main body structure.

To enhance side-impact protection, ultra-high-strength steel plate (980 Mpa level) is used for the B-pillar and side sill structures to improve the local cabin area rigidity. In addition, two door impact beams are placed within each front and rear door. By optimally positioning the beams in relation to the door’s internal structure, a sufficient crush space is ensured to minimise intrusion. Furthermore, a ‘door catcher’ is fitted to prevent the bottom of the rear door from deforming into the cabin – particularly in rear impacts.

Despite the relatively short rear overhang, the Subaru Outback’s structure is optimised so that rear impact energy is efficiently absorbed by controlled and gradual crushing of the rear sub-frames.

‘Passive’ safety advances that also benefit pedestrians

While a robust structure can form the foundation for a truly safe car, Subaru has also ensured that the Subaru Outback is comprehensively kitted out with a full range of both ‘passive’ and ‘active’ safety equipment – as the best way to prevent occupant injury is to overcome the hazards of daily motoring and avoid any accident in the first place.

The new front seats have significantly-stiffer frames and inner-structures to provide protection against whiplash injuries without having to fit ‘active’ head restraints. New-design, energy-absorbing head restraints offer greater protection by reducing head impact forces.

Front, side and curtain airbags are fitted as standard. The side and curtain airbags are enlarged for enhanced performance, and the airbag impact sensors have been upgraded to improve responses.

To protect the driver’s knee and lower leg, the steering column’s structure has been redesigned with an impact-absorption space, and a knee protector is fitted. All the foot pedals and the driver’s footrest have a collapsible function (above a pre-set g-force) to reduce the likelihood of foot injuries.

The issue of pedestrian protection has also been addressed. New, impact-absorbing materials and an optimised structure around the front bumper have made it possible for the new Outback to clear the next-generation European pedestrian protection standards, which are the most stringent in the world.

Although steel is used for the hood (to maximise protection of the car’s occupants), the impact-absorbing space beneath the hood and above the low boxer engine is enlarged, and the structure is improved around the body cowl to reduce possible injury to a pedestrian.
